Overview
Kattobi KEIKYU Rider is a high-tempo Keikyu Railway collaboration track composed by Shinji Hosoe under his Sampling Masters MEGA alias, with lyrics by Nima. and vocals by Tomoe Tamiyasu. Originally created for CHUNITHM STAR, the song captures the exhilaration of riding a Keikyu express train (快特, kaitoku) through densely packed lyrics filled with railway terminology, station announcements, and playful route directions.
The song was added to maimai FiNALE on February 7, 2019, as part of the ONGEKI & CHUNITHM crossover category. The maimai version runs approximately 2:25, slightly shortened from its CHUNITHM original. Jacket art features Tsukui Shizuno, a CHUNITHM character, in Keikyu-themed attire.
The MASTER chart, designed by Tamagodoufu (玉子豆腐), is notable for a heart-shaped (♡) Slide formation that visually mirrors the lyric "びっくりキュンキュン飛び出すハート" (surprising, heart-pounding flying hearts). At difficulty 13+ (constant 13.7), it demands strong stamina and precise Slide execution, the chart contains 184 Slide notes out of 844 total. The EXPERT chart, designed by Happy (はっぴー), offers level 13 (constant 13.2) difficulty with a more conventional note distribution. Both charts were re-evaluated upward over successive maimai versions as the community recognized their true difficulty relative to peers.
